摘要:

中微子振荡的发现表明中微子具有质量并发生混合,因此必须扩展标准模型,而这可能需要引入中微子非标准相互作用(NSI)。我们研究高能μ子对撞机探测此类涉及μ子的NSI的潜力,特别关注μ子力。通过分析过程$μ^+ μ^- \rightarrow ν\overline{ν} γ$产生的单光子信号,我们探索涉及两个μ子和两个中微子的四费米子接触相互作用。此外,我们考察产生标量和矢量媒介NSI的最小模型,并研究其唯象学。在质心能量3 TeV、积分亮度$\mathcal{L}=1$和$10~\mathrm{ab}^{-1}$条件下,给出95%置信水平下NSI强度$ε_{αβ}^{μμ}$的预期灵敏度,展示μ子对撞机与其他实验探测之间的互补性。

英文摘要:

The discovery of neutrino oscillations implies that neutrinos are massive and mixed, necessitating an extension of the Standard Model, which may require the introduction of non-standard neutrino interactions (NSI). We investigate the potential of a high-energy muon collider to probe such NSIs with muons, specifically focusing on muonic forces. By analyzing the monophoton signal from the process $μ^+ μ^- \rightarrow ν\overline{ν} γ$, we explore four-fermion contact interactions involving two muons and two neutrinos. Moreover, we examine minimal models that generate scalar and vector-mediated NSIs and study their phenomenology. Projected sensitivities for the strength of NSIs, $ε_{αβ}^{μμ}$, are presented at a 95$\%$ confidence level for a center-of-mass energy of 3 TeV and integrated luminosities of $\mathcal{L} = 1$ and $10~\mathrm{ab}^{-1}$, showcasing the complementarity between a muon collider and other experimental probes.
